Yorkview was an Ontario provincial electoral district (riding), in the former city of North York from 1963 to 1999. The riding was established for the 1963 Ontario general election. The riding was abolished in preparation for the 1999 Ontario general election. It was partitioned into the current provincial ridings of York West, York Centre and York South—Weston. Its first and longest-serving Member of Provincial Parliament (MPP) was Fred Young, who served the riding as an Ontario New Democratic Party (NDP) member, from 1963 until his retirement in 1981. The last MPP to represent the riding was Ontario Liberal Party member, Mario Sergio. Sergio went on to win the first election of the new riding of York West, which contained the majority of the former Yorkview riding.
